Memory Timing
• About four seconds after the end of operation
• When entering the STANDBY status through remote operation, through the operating panel of
the main unit, or by issuing an RS-232C command
• When switched to Menu mode as a result of a MENU button action
• When switched to RS-232C adjustment mode by an <AJY> command
NOTE: Among the RS-232C commands available in Normal operating mode, some are not stored
in last memory when used in this mode. See “5.5.1 About the RS-232C Adjustment Mode.”
• Approximately four seconds after the end of operation
• When entering the STANDBY status through remote operation, through the operating panel of
the main unit, or by issuing an RS-232C command
• When returning to the previous screen with the SET button
• When exiting Menu mode with the MENU button (restoring the unit to Normal operating mode)
• When exiting Menu mode with the KEY LOCK/UNLOCK button (switching unit to Normal operat-
ing mode and entering the KEY LOCK status)
• When switching to RS-232C adjustment mode with an <AJY> command
• When switching over to another input signal mode (i.e., to another signal frequency).
• When automatically exiting Menu mode after persistence of no-signal status for approximately
eight minutes (restoring the unit to Normal operating mode)
• Approximately four seconds after the end of operation
• When entering the STANDBY status through remote operation, through the operating panel of
the main unit, or by issuing an RS-232C command
• When returning to the previous screen with the SET button
• When exiting Integrator mode with the MENU button (restoring the unit to Normal operating
mode)
• When exiting Integrator mode with the KEY LOCK/UNLOCK button (switching the unit to Normal
operating mode and entering the KEY LOCK status)

• When automatically exiting Integrator mode after persistence of no-signal status for approxi-
mately three minutes (restoring unit to Normal operating mode)
• Approximately four seconds after the end of operation
• When entering the STANDBY status through remote operation, through the operating panel of
the main unit, or by issuing an RS-232C command
• When changing adjustment or setting items using PC commands
• When exiting RS-232C adjustment mode with an <AJY> command (restoring the unit to Normal
operating mode)

Normal operating mode and invoking KEY LOCK status)

5.1.5 Last memory
The last memory timing used by the unit is given in the table below. Remember, no last memory function is executed
if you perform the following without meeting these timing requirements:
• Switch off main power
• Unplug the power cord from the outlet; and
• Switch off the outlet breaker.
Before Beginning Adjustments
NOTE: If you start or stop the entire system by switching a breaker on or off, allow enough time for the last memory
function to perform by satisfying the timing requirements given above. Note that this practice causes count
errors on the hour meter.
5.1.6 Aging
After switching on power to the unit, input signals to perform aging until the unit stabilizes. Use signals that are unlikely
to cause the displayed images to be “burned” onto the screen: signals such as a 100% white signal or animations from
LDs are recommended. This should take about thirty minutes. This ensures precision adjustments.
NOTE: Display of still images over extended periods can lead to the above-mentioned “burning.”
